Tony Tyler, CEO of the International Air Transport Association (IATA), attends a press conference at the ICAO headquarters on February 4, 2015 in Montreal. An international aviation summit gave strong backing Wednesday to a plan to have all commercial flights emit a distress signal every minute in emergencies, in response to last year's Malaysia Airlines disaster. A large majority of the International Civil Aviation Organization (ICAO)'s 191 member states are in favor of implementing the plan as soon as possible, said officials, paving the way for its adoption next year. The plan was prompted by last year's disappearance of Malaysia Airlines flight MH370 en route from Kuala Lumpur to Beijing in what remains one of history's great aviation mysteries.
